HI Chris, The OSG cull traversal builds a rendering graph that contains a list of all the Drawable leaves and the StateSet's associated with them, some of the objects might not actual render any pixels but there bounding volumes will be in the view frustum so it'll be a conservative list.
If you really need to know whether pixels from drawable make it into the frame buffer then you'll needs to the occlusion query test that the OSG supports. See the osgocclusionquery example for inspiration. Robert. On 11 November 2013 17:42, Chris Stankevitz <[email protected]>wrote: > I spent 10 minutes googling this.
